HEEL TRIMMlNG MACHINE.

SPECIFICATION forming-part of Letters Patent No.357,740, dated February 15, 1887.

Application filed June is, 1886. Serial No. 205,203. (No model.)

- T all whom it may concern.-

Be it known that I, CHARLES H. TRASK, of Lynn, in the county of Essex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in HeeLTrimming Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention is an improvement upon that described in my application for Letters Patent of the United States executed June 2, 1886, filed June 7, 1886, Serial No. 204,824, and it relates to various details of construction and organization, all of which will hereinafter be described.

In the drawings, Figure l is a front elevation of a machine containing the features of my invention. Fig. 2 is a right side elevation thereof. Fig. 3is a plan viewof the machine. Fig. 4 is a vertical section, enlarged, of the heel-trimming cutter and adjacent parts. Fig. 5 is a view in elevation of the front part or section of the l1eel-trimming cutter. Fig 6 is a view in elevation of the rear section or part of the heel-trimming cutter. Figs. 7 and 8 are side elevations of the cutter, showing the two sections together in one view and slightly separated in the other. Fig. 9 is a view in front elevation of the rand-cutter.

The sole-edge cutter A, the shank-edge cutter B, and the heel-edge trimmer or cutter O are supported upon their respective shafts, a b c, which are carried by the bracket A, and are operated as described in my said application. The sole-edge cutter and the shankedge cutter are mounted upon their shafts substantially as therein described. The heeledge cutter C is represented as made in two parts or sections-the rear part or section, 0, and the front part or section, C The rear section, 0, is shaped as represented in Figs. 4., 6, 7, and S. It is formed from a disk or circular blank or plate, 0, which has a series of teeth or cutters, 0 formed therein, to be of the same length, and preferably the thickness, of the disk or block; and it also has another series of teeth or cutters, 0 which are formed to project laterally from the plate or disk 0, and. these groups of teeth c c are arranged in shape to the section Gthat is, itis also made from a blank having a disk or plate, 0, upon one side of which is formed the short teeth or cutters c and upon the other side of which is formed the longer teeth or cutters a, and when the two sections of the cutter are together the long teeth of one section form continuations of the short teeth of the other, as represented in Fig. 7. The surface of the cutter may have any desired shape or curvature, and it is governed, of course, by the shape which it is desired to give the finished heel.

The rear section, 0, has holes 0, for the reception of the screws 0 which look it to the collar 0 arranged to slide on the shaft 0. This collar has a long sleeve, 0 which surrounds the shaft 0 and extends into the sleeve or box 0 and a recess, a, in which the top-lift rest and guide is movable, as hereinafter specified. The section G of the cutter is secured to the end of the shaft cagainst a shoulder, 0, formed thereon by means of the screw-stud c. The rand-cutter c, and the rand-guard c are attached to the section 0 of the heel trimmer or cutter, as described in my said application, and are adjusted as therein set forth. The top-lift rest and guard D is suspended from the rod or stud cl, which extends horizontally outward from the bracket A, and it is arranged to slide thereon, a wide bearing being provided by means of the sleeved. It is moved inwardly with the rear section, 0, of the cutter, and away from the front section, 0 of the cutter, by the pressure of the bottom of the heel against the pressure of the spring a, and this spring serves to return the top-lift rest and guide and the section 0 of the cutter horizontally to their original position upon the removal of the heel, and also to keep the top-lift rest constantly in contact with the bottom of the heel as the heelis being trimmed.

At the right side of the heel-edge cutter there is a heel-edge rest, E, which is carried by the rod 6, which also supports the arm 6, to which is attached the plate, bar, or rod 6 for adjusting the rand-cutter B of the shankedge cutter. The bar, rod, or support a" is made adjust-able upon its supporting-arms e to move the rand guide and cutter of the shankedge cutter.

In operation the sole and shank are trimmed substantially as described in my said application. In trimming the heel the bottom of the heel is placed upon the top-lift rest, with the edge of the top lift bearing upon the top-lift guide and the side of the heel-rest upon the surface of the heel, the rand-guard entering the crease above the rand. This placing of the heel IIlOVQS' DhG top-lift'rest and guard and the section 0 of the cutter to provide the cutter' with a Width or length sufficient to trim the section of the heel then presented to it.

7 As the heel is moved the section 0' is auto- 5 O 0 the part 0 having the two groups of teeth c c and the part C having corresponding groups of teeth arranged in relation to the section 0, so that its short teeth form continua tions of the long teeth of said section, substantially as described.

2. The combination, in a heel-trinin1ing machine, of the rotary cutter comprising the sections C 0 the stationary heel-rest E, and the non-rotating top-1i ft rest and guide D, substantially as described.

3. The combination of the heel-trimmingcutter O G", the shanlcedge cutter B, the rod or stud e, the heel-rest E, the arms 6', depending from said rest, and the rand-guard and shank-trimming cutter attached to said arms, all substantially as described.

4. Thecombination,inatrimming-machine, of the section C of a cutter, the independent rand-knife 0*, the independent rand-guard 0, both attached to said section C of the cutter, to revolve therewith, and the section O of the cutter movable t0 and from the section 0 and a heel-rest, E, substantially as described.
